' To all whom it concern.

Be it known that I, SAM EL M. MAYER, a citizen of the United States, anda resident of Long Island, New York, in the county of Nassau and Stateof New York, have invented certain new and useful Improvements in PocketDrinking-Cups, of which the following is a specification.

The invention relates to a pocket drinking cup which may be composedpartly of reinforcing material and partly of flexible,waterproofmaterial.

It has for its object to provide a simple and inexpensive drinking cupwhich may be collapsed to flat form. The cup is preferably composed ofsuitable impervious material which may be properly reinforced bycard-board, metal or other suitablematerial but so arranged that thecontents thereof need not come in contact therewith, the design beingsuch as to securely retain and protect the flexible material comprisingthe cup proper.

A further object of the invention consists in means to prevent thecollapse ofthe cup when in use, said means serving at the same time toopen the cup to its full extent when released. A still further object ofthe inv vention consists in providing a cup which may close in suchmanner as to prevent the entrance of dirt or other foreign material;and, when closed, to adequately protect the interior flexible materialportion. The improved cup is simple, substantial and may be manufacturedat low cost, is eflicient in use and, being in fiat form, isconveniently carried in a pocket when not in use. A still further objectof the invention is to provide a construction which will admit ofconvenient and ready replacement of the impervious, cup-formingmaterial.

In the accompanying drawings which illustrate the invention Figure 1 isa plan view of thecup in closed condition.

Fig. 2 is an edgewise view thereof.

Fig. 3 is a perspective view showing the cup in open position ready foruse.

Fig. 4: is a vertical section through the cup in opened condition.

Fig. 5'is a development of the blank forming the cup proper.

Similar characters of reference designate corresponding parts throughoutthe several views.

Referring to the drawings, the novel cup longitudin cup-forming anerably backed and reinforced in whole or in part by two metal orcard-board reinforcing slide members 10 and 11. For example, the edgesof the reinforcing members, when metal is emdployed, may be turnedinwardly over the e es of the cup material to securely hold saidmaterial; or when card: board or the like material is employed, thesame, may be secured thereto as by an adhesive. The cup forming memberis designed to be further retained, if desired, between correspondingcovers 12 and 13 of substantial material andpwhich are hingedly securedalong the bottom edge and arranged-to be distended by means of a spring1 1. At the cut and upper edges, the hingedm'embers may be secured as bymeans of a clasp 15 attached to one of the reinforcing members andadapted to fit over the top edge of the other.- For the purpose ofremovably receiving said members 10 and 11, the covers may in whole orin part be turned over along their longitudinal edges to afford suitableguides or ways.

The blank, cut as shown in Fig. 5, is designed to be made up into aliquid-tight receptacle 16 which is arranged to be backed in anysuitable manner by the respective members 10 and 11 and securely heldthereby. r

To this end, the blank is creased as indicated by the broken lines, Fig.5, and is then folded longitudinally along the lines ab, c-d and ae, c-fand transversely along the line ac, the end flaps 17, 18 being suitablysecured to each other as by an adhesive; and, similarly, the upturnedbottom flaps 19 are secured to the overlapping flaps 17 18.

In this manner a simple form of blank is utilized to provide a suitableangularly formed container for liquid. The material composing thecontainer may be of any suitable paper or cloth material renderedimpervious as by oiling or parafiin, or in any other suitable manner-UThe cup 16 thus provided is readily inserted into the hinged receptacleformedyby the covers 12 and 13, by partly closing the latter, as inpressing same together, and then sliding the cup 16, with or withoutsuitable backing, into guideways provided as by turning over the edgesof said covers.

When the clasp 15 is released, spring 14 will automatically serve todistend the cup, making it suitable for receiving liquid; and when it isdesired to fold up the cup, this may be readily accomplished by simplyexerting pressure upon the covers, the inner cup member closing more orless as a bellows. By then securing the clasp 15 over the cooperatingupper edge of the wall 13, the cup is retained in flat folded form asshown in Fig. 2, the covers being maintained substantially in parallelrelationship and adequately protecting the interior and flexible portionof the cup proper, as well as providing against the entrance of dirtthere- .to. -.The edges of the 'cu-p may be more or less rounded toprovidea smoothly finished article which can be' conveniently carried inthe pocket. The catch at the tophas been so arranged that in holding thecup in its natural position in the hand one can, by a'slight move.- mentof the thumb upwardly, release the catch and open the cup. This allowsfreedom'of the other hand to open a faucet, etc,

The cup can likewise, be closed by squeezing together and droppingrthecatch in place.

I claim: 1. A hinged enveloping contrivance adapted to detaohably securea flexible container, comprising two flat member hingedly secured at thebottom, and means to lock the members to each other, said members havingsuitable vertically directed guideways into. which the said flexiblecontainer is adapted to slide.

2. A hinged enveloping contrivance adapted to detachably secure aflexible container, comprising two flat members hingedly secured at thebottom, and means to lock the members to each other, said members beingadapted to slidably receive reinforcing mem-.

bers secured to the ends of the flexible cdntainer. v

- 3. A hinged enveloping contrivance adapted to detachably secure aflexible container, comprising two fiat members hingedly secured at thebottom, and means to lock the members to each other, said members havingtheir vertical edges turned inwardly to provide guidewa'ys into whichthe ends of the said flexible containerare adapted to slide, and aspring tending to separate the members at the top.
